Purpose and description of task (project)
To maintain reservoir pressure (PPD), water is pumped, initially industrial water from the intake wells of the Albsenomanian horizon. Due to the increased water availability of wells, the raw material separated from the oil is cleaned at the water treatment plant and pumped through the PPD system into the reservoir. When pumping mixed technical and raw water, precipitation of iron oxide occurs, which leads to a discrepancy in the quality of water for flooding with the requirements of ST RK 1662-2007: The existing technological scheme of water treatment at the installation cannot ensure the appropriate water quality according to the requirements of ST RK 1662-2007 (in terms of the content of mechanical impurities and petroleum products)
specialized water filtration equipment
Accumulation of deposits of mechanical impurities in the tubing, which leads to the retention of hydrogen sulfide in the pipes. Contamination of the Bottom-hole Zone of the Well (CCD), resulting in a decrease in pick-up and an increase in pressure in injection wells and reservoirs. The scale of the problem is the impact on the entire cycle: pipes, pumps, valves, etc.
The quality parameters of reservoir water preparation for injection into injection wells do not meet the requirements of ST RK 1662-2007 "Water for flooding oil reservoirs. Quality requirements". The content of mechanical impurities is 75-173.5 mg/l for the entire period of operation of the UPRV, at a rate of 15 mg / l. Since 2011, the actual capacity of the installation exceeds the design by more than 2.5 times 60mz /h, at a design rate of 25m3 / h.
